The State President of the Republic of South Africa was the head of state of South Africa from 1961 to 1994. The office was established when the country became a republic on 31 May 1961, outside the Commonwealth of Nations, and Queen Elizabeth II ceased to be Queen of South Africa. The position of Governor-General of South Africa was accordingly abolished. From 1961 to 1984, the post was largely ceremonial. After constitutional reforms enacted in 1983 and taking effect in 1984, the State President became an executive post, and its holder was both head of state and head of government.

South Africa, officially the Republic of South Africa, is the southernmost country in Africa. It is bounded to the south by 2,798 kilometres (1,739 mi) of coastline that stretches along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 62 million people, the country is the world's 23rd-most populous nation and covers an area of 1,221,037 square kilometres. Pretoria is the administrative capital, while Cape Town, as the seat of Parliament, is the legislative capital. Bloemfontein has traditionally been regarded as the judicial capital. The Constitutional Court, the country's highest court, is located in Johannesburg.
